Smart card in another box

I have telewest with sky sports etc., Im visiting my gran this weekend, she also has telewest but no sky sports.

Does anyone know if i can just take my smart card out and use it in my grans STB and get my sky sports.

I dont see why not as i can still only watch it in one place.

I phoned telewest but the guy just told me it was illegal becuase then i could watch sky sports in two houses at once , i tried to explain that i couldnt cus id take the smart card, hence disabling the STB, but he didnt seem to grasp the concept so i politely ended the call

If anyone replies could they confirm wether they have done this or are just guessing? Ive already guessed i can.

No, you won't be able to do this; as TomM stated, the smartcard is 'paired' to your set top box, and so you'll just receive a message telling you that the smartcard is invalid.

The reasoning behind this is to prevent fraud. Although (as far as I am aware) it is not possible to 'copy' a smartcard as yet, if it did ever become possible, this pairing of cards to boxes would prevent any unauthorised copies of smartcards being used.

Although you're not strictly supposed to .... there's nothing to stop you!

(and yes, it will work fine)

I have tried this and it worked in my grans house but that was when she had analogue, now that she has digital i tried it and only got front row ads on every single channel. Also i tried the smartcard thing, it decrypts the channels that are paid for on the smart card but you just get a blank screen and a smart card invalid message so it's not really worth the hassle and i know how you feel about having less channels at your grans, i even persueded her to upgrade to more channels but i just got a reply that it costs too much money

Not to turn this into a hacking thread but there it certainly is possible to hack digital cable and quite easily from what I've read online. There are forums which told how to hack digital cable over a year ago. Mainly from the same people who were leaders in the whole onDigital / itvDigital hacking.
